For 6 servings
Measure all ingredients: In a medium bowl or a jar with a tight-fitting lid, combine the fresh lemon juice, Dijon mustard, dried tarragon, granulated sugar (if using), sea salt, and freshly ground black pepper.
Whisk or shake to combine: If using a bowl, whisk the ingredients together until well combined. If using a jar, secure the lid and shake vigorously for about 15-20 seconds.
Emulsify the oil: Slowly drizzle the extra virgin olive oil into the lemon juice mixture while continuously whisking vigorously. If using a jar, add the olive oil, secure the lid, and shake vigorously for another 30-45 seconds until the mixture is thick and creamy.
Check consistency and taste: The vinaigrette should be emulsified, appearing slightly thickened and opaque. Taste and adjust seasoning as needed, adding more salt, pepper, or a tiny pinch of sugar if desired to balance the flavors.
Rest and serve: For best flavor, let the vinaigrette sit for at least 10 minutes before using to allow the flavors to meld. Whisk or shake again just before serving.
Storage: Store any leftover vinaigrette in an airtight container in the refrigerator for up to 5-7 days. The oil and acid may separate upon standing; simply whisk or shake well to re-emulsify before each use.
What to keep in mind.
4 tips from the recipe — small details that make a real difference to the final dish.
- 1Use fresh ingredients: Always opt for freshly squeezed lemon juice over bottled for the brightest flavor. If you have fresh tarragon, use 1 tablespoon of finely chopped fresh tarragon instead of dried.
- 2Adjust to your taste: This recipe is a guideline. Feel free to adjust the ratio of oil to acid, or the amount of salt, pepper, and sugar to suit your personal preference.
- 3Emulsification trick: If your vinaigrette isn't emulsifying well, add another 1/2 teaspoon of Dijon mustard and whisk/shake again. Dijon is a great emulsifier.
- 4Room temperature oil: Using olive oil that is at room temperature can sometimes help with better emulsification compared to very cold oil.
Adapt it for your goals.
